zeekay bb29503e53 fix(crypto): real Lagrange aggregation, proper ECDSA sign shares, FROST Schnorr verification ...

Replace placeholder XOR aggregation and stub implementations with real
cryptographic operations:

- CGGMP21 NonceGen: generate random secp256k1 scalar k, compute R = k*G
- CGGMP21 SignShare: partial ECDSA signing with Lagrange coefficients
  s_i = k^(-1) * (m + r * d_i * lambda_i) mod n
- CGGMP21 Aggregate: sum partial signatures with low-S normalization and
  recovery byte v for Ethereum compatibility
- CGGMP21 Verify: full ECDSA verification using secp256k1 curve arithmetic
- FROST Aggregate: sum s_i scalars with consistent R commitment validation
- FROST Verify: BIP-340 tagged-hash Schnorr verification (s*G == R + e*P)
- Helper functions: Lagrange coefficients at 0, point compression/decompression
